Flexible iris retractors for management of zonular dialysis during planned phacoemulsification.

Author information

Department of Ophthalmology, Chang Gung Memorial Hospital. 222, Maijin Rd., Anle Chiu, Keelung, Taiwan 204, ROC.



The aim of this study was to determine the use of flexible iris retractors in four patients with zonular dialysis occurring during cataract surgery.


We describe the use of flexible iris retractors to stretch and fixate the capsulorhexis over the zonular dehiscence sector for patients with traumatic zonular disruption occurring during phacoemulsification, which stabilizes the capsular bag and facilitates cataract extraction without complications.


Each of the four eyes was implanted with posterior chamber intraocular lens (PCIOL) successfully. The intraocular lenses (IOLs) remained well centered during the 12-month follow-up period and the patients enjoyed improved vision without complications.


Flexible iris retractor is a simple, convenient and useful instrument for managing zonular dehiscence that occurred during cataract extraction. It facilitates the removal of the residual lens material and IOL implantation without major complications.
